The invention relatesto an outboard motor for light boats and moreparticularly to -motors of this class to be fastened by the side of theboard of the boat, quickly and readily. Ac-

cording to the invention the motor with all its accessories forms aself-contained block which also comprises the means intended for placingthe whole set on a pin-shaped carrier integral with the boat. Thefastening means consist in a laterally projecting sleeve enclosing thecarrier pin and adapted to be immobilized on the same by a simpleattachment such as a bayonet-joint and elastic means. An essentialfeature of the invention is further the particular arrangement l5 of theseveral parts of the set on the block so that a good accessibilitythereof is secured, and the fact that the motor is horizontal and itslongitudinal axis parallel or almost parallel to that of the propellershaft so that, .when the motor is running, any shocks produced re takenup by the thrust of the propel1er. o the system of transmitting thetorque from the motor to the propeller shaft and the arrangementprovided for y 'water cooling are particularly advantageous.

The drawings represent an out-board motor corresponding to the presentinvention and in which by way of example Fig. 1 shows a vertical sectionthrough the whole set as taken about the line I-I of Fig. 2, some partsdisposed infront of the plane of sec- .tionbeing shown by dotted lines,

Fig. 2'shows a section on line VII-lI of Fig. 1, Fig. 3 is an end viewof the motor, Fig. 4 is a longitudinal section of a modification of thefastening attachment, and

Fig. 5 the corresponding outside view thereof, Figs. 6, 7, and 8 showthe end of the fastening attachment in several dilerent positions.

The out-board motor comprises the enginecylinder 4, the crank case 5, aflywheel magnet 6, a starting appliance 1 fastened to the flywheel, thepropeller shaft 8, the fuel tank 9 placed above the engine cylinder, amuiller 25 arranged by the side of and directly connected to the motorand a carbureter Ill, all these items being combined jects a'sleeve I I,the bore of Awhich is intended to be pushed over a pin-shaped or tubularcarrier, e. g. a tube I2 with'which the h ull of the boat is provided,so as to carry' the motor set. A clutch I2a is provided between thesleeve II and the tube I2, said clutch having one element l I3aconnected to the outer end of the sleeve II and the other element in theform of a flange I3V connected to the tube I2. Between the bottom of toa block. From the crank case 5 laterally pro-` the bore of the sleevelII and the end of the carrier I2 there is interposed a spring member I4by which an elastic union is established between the tube I 2 and thesleeve II. The propeller shaft 8 is arranged transversely to the engineshaft and parallelly to the axis of the engine cylinder 4 itsdrive beingaccomplished through the intermediary of a worm or helical gear I 5 thereduction ratio of which is one half. 'I'he water circulation is securedby holes I6 of the propeller I'I and the hollow shaft 8 While the freshWater is taken up by a trunk I8 which can, unless used, be swung towardsthe motor about a pivot I9 as shown by dotted lines in Fig. 1.

With this arrangement every part of the outboard motor is readilyaccessible as the latter is open on lall sides and the several partsthereof are easily detachable froinone another so that they aresusceptible of easy repair or change in case of damage. The attachmentprovided for fastening the motor to the boat is disposed at a point anddesigned in a way not interfering with the accessibility of the otherparts of the set. Moreover the sleeve II is by a carrying yoke 20connected to union rails 2| fastened to the motor so that the structureis further stiiened.

In the embodiment shown by Figs. 4 and 5 the free end of the sleeve I0is provided with an enlargement I2' which is to enclose a ange I3'fastened to the carrier II', e. g. by spot welding.' At its front endthe enlargement I2' is closed by a lid I4 secured on the said sleeve inany suitable manner. On its outside face the ange I3' is provided witha' radial knife-like rib I5 and ac cordingly the lid I4 carries on itsrear face several, e. g. two radial grooves I 6 of a similar trlangularcross section. The depth of the enlargement I2' is so proportioned thatthe ange I3 can be pushed inward by the carrier II being displaced, inwhich case the rib I5' leaves the groove I6' and is prepared to enteranother groove when the carrier Il' has been turned and so the motor maybe adjusted to another inclination. This engagement may be positivelymaintained by a nut I8' disposed outside the lid I4 on a thread of thecarrier tube I I' and pressing the iange I3' rmly against the .lid I4.

The flange I3 is not round but provided with e. g. two sector-shapedprojections (Figs. 6, '1, 8)

whereas the lid I4' has corresponding recesses Isf 50 through whichthe-projections of the ange I 3' can be passed so as to be caused, whenthe carrier tube II' has been turned, to bear against the solid portionsof the lid I4', the rib I 5' being at the same time introduced into oneof the 55 2. grooves i6' which establishes a sort oi bayonetjoint bywhich the parts I3 and il* are secured not only to each other in alengthwise direction but also against relative angular displacements.

The invention claimed in the present applicar-l tion relates primarilyto the means for mounting the motor on the boat. v Other novel featuresillustrated are claimed in my divisional application -Serial No.118,167, led December 29, 1936.

What I claim, is:-

1. In combination Vwith an outboard motor unit;

a bearing sleeve attached'to said unit, a rod-like member adapted to besecured to the boat and having a bearing t in the interior of said.sleeve, a clutch, one element of which is connected to the outer. end ofsaid sleeve, the other. elementr being connected to the rod-like memberfor interconnecting saidrod-like member and said bearing member againstrelative rotational movement,

and a spring in the interior of said sleeve between the outer end ofsaid rod-like member and the inner end b! said sleeve for urging theelements of the clutch together and for effecting a :iie'xible axialconnection between said fsleeve and said rod-like member. l

2. In combination with an 'outboard motor unit, a sleeve xed to saidunit and extending laterally therefrom, a rodllike member adapted to beseplate having facing interlocking surfaces, and a member khavingthreaded engagement with said rod-like member for moving said sleeveaxially to bring said flange and plate into interlocking en-` gagementagainst relative rotation.

3.- In combination with an outboard motor unit, a rod-like memberadapted to be secured to the boat, a bearing sleeve attached to saidunit, embracing said rod-like member and movable axially therealong, aclutch, one element of which is connected to said sleeve, the otherelement being connected to said rod-like member 'for interconnecting'said sleeve and said member against relative rotational ovement, andspring means for urging the elements of the clutch together and foreffecting a flexible axial connection between said sleeve and saidrod-like member.

4. In combination with an outboard motor a sleeve xed to said unit andextending laterally therefrom, a rodi-like member adapted to be securedto the boat and having a bearing iit in the interior of said sleeve,said sleeve and said rodlike member `being relatively movable axially, aclutch between said sleeve and said rod-like member and having oneelement connected to said sleeve and the other element connected to saidrod-like member, and an annular member having a threaded engagement withsaidrod-like member and engaging the clutch element connected to saidsleeve formoving said sleeve axially to bring the two clutch elementsinto interlocking engagement against relative rotation, and for` lockingsaid elements in said interlocked position against relative axial androtational movement.
